Calm Ishigaki drop-off with rich macro life
Hanazawa Drop is a boat-access Ishigaki macro dive with a classic drop-off feel and a small-root focal point that rewards slow, careful searching. The site is easy in calm water but still feels like a real reef edge, so the best dives are the ones where buoyancy, trim, and the day's line all stay tidy. You are not here to rush the route; you are here to move slowly, watch the cleaning action, and let the shallow-to-deeper transition do the work.
Site Conditions
Safety Notes
Stay on the briefed route and keep an eye on weather. Yonehara can carry stronger currents, and the beach area has no lifeguards or jellyfish nets.
Access Restrictions
Best approached as a guided boat dive. The site is easy on calm days, but the drop-off and bay conditions still reward local guidance.
Community notes to help plan your visit.
Scuba Diving
An easy site with calm currents, suitable for beginner and intermediate scuba divers.
Freediving
Not a freedive-first target. The better use case is relaxed scuba or photo diving with good buoyancy control.
Snorkeling
The wider Yonehara area works for snorkeling, but Hanazawa Drop itself is mainly a scuba site because the key feature sits deeper.
